There's not much to say here. The intel EtherExpress pro 10/100 is a kernel option. Compile eepro100 (either directly in the kernel or as a module and insmod it). It works. Yes, it's that easy.

Configuring the wireless network

• Kernel Configuration
  You want to enable the following in your kernel (I'm giving this to you in terms of where you'd find it if you did make menuconfig in your /usr/src/linux directory. I assume if you're editing the .config file by hand you can figure out what to enable on your own):
  • Under General Setup, enable "Support for hot-pluggable devices" and then "PCMCIA/CardBus support ---> CardBus support".
  • Under Network Device support > Wireless LAN (non-hamradio) ---> enable "Wireless LAN" and choose "Hermes chipset 802.11b support" and then "Hermes PCMCIA card support"
• Install the Linux PCMCIA Card Services. After compiling your kernel, as pcmcia-cs looks at your kernel configuration (at leat under gentoo) to get information. Add pcmcia to your default runlevel.

  A problem I had when I first installed pcmcia-cs and added it to the default runlevel is that it would hang for approximately a minute or two at "starting pcmcia ... cardmgr: watching 2 sockets" and then go on. This made my machine boot really slowly. I discovered that this was because it was trying to connect via the wireless lan interface, and couldn't do so (as most of the time I'm not around a wireless lan), but would sit around transmitting into nowhere for a while. My inelegant solution was to edit /etc/pcmcia/network and to comment out the $ACTION lines so that pcmcia didn't try to start any network services itself. I do that myself via quickswitch anyways.

• Install the Wireless Tools for Linux.
• The wired network is eth1.
• Want to see if it's working? cat /proc/net/dev. You should see 3 interfaces listed: lo, eth0, and eth1. If you try and do anything with eth1 (eg dhcpcd eth1) you should see that you're transmitting stuff (even if there's nothing to receive them).
• If you're like me, you probably have a million different network configurations. I have a static IP address through wired ethernet at work, a DHCP connection through wires at home, the ability to connect to the experimental campus wireless network at a couple of points on campus, friends with wireless networks .... et cetera. A great utility for switching network configurations is quickswitch.
  Here's a copy of my /etc/quickswitch/switchto.conf file.
